Unit 32, Colorado

The unit spans from the Colorado River corridor at roughly 5,000 feet elevation up to the Roan Plateau rim at approximately 9,290 feet. The Roan Cliffs rise nearly 4,000 feet above the Colorado River Valley. The plateau top is a broad mesa of approximately 70 square miles broken by numerous deep canyons and drainages cutting to lower benches. The southern portion near the river is characterized by rolling sagebrush flats and steep-sided canyon walls. Overall topography is glassable but access into canyon bottoms and upper plateau drainages requires significant physical effort. Roads become impassable in wet weather and snow closes higher routes above approximately 8,000 feet.

Public land (BLM, approximately 38% of the unit) is concentrated in the eastern portion around Government Creek and across the Roan Plateau itself. The Colorado River Valley BLM Field Office (2300 River Frontage Road, Silt, CO 81652; 970-876-9000) administers access. Two primary vehicle routes reach the plateau: (1) JQS Trail (County Road 242), accessed approximately 1 mile north of Rifle on CO-13 — a narrow, tight-switchback 4WD route to the plateau top, unsuitable for trailers. (2) Cow Creek Gulch Road, accessed from CO-13 via County Road 5 (Piceance Creek Road) north of Rifle toward Meeker, then west on Cow Creek Gulch Road to the plateau — a more accessible alternative. An OHV permit is required on BLM lands; out-of-state OHVs need non-resident registration. Heavy oil and gas service-truck traffic is common on all secondary roads. Approximately 62% of the unit is private land, concentrated in the lower creek drainages and canyon-bottom ranches — hunters must verify boundaries carefully. There is no designated Wilderness and no National Forest land within GMU 32.

Lower elevations (below approximately 6,500 ft) are dominated by pinyon-juniper woodland with pockets of sagebrush and bitterbrush. Mid-elevation benches and drainages carry oakbrush, mountain mahogany, and ponderosa pine. The upper Roan Plateau transitions into sagebrush parks interspersed with aspen stands and pockets of spruce-fir. Riparian corridors along Parachute Creek and Government Creek support cottonwood, willow, and irrigated crops that attract elk and deer at dawn and dusk. The unit contains rare endemic plant communities — including hanging garden sullivantia and Parachute penstemon — in the Roan Plateau Area of Critical Environmental Concern (21,034 acres designated in the BLM's 2008 Resource Management Plan).

Mule deer inhabit the unit year-round, using higher pinyon-juniper and sagebrush country in summer and migrating to lower-elevation canyon benches and creek drainages in winter. Elk use the upper Roan Plateau and timbered aspen/spruce zones in summer and transition to lower sagebrush/oak benches during autumn hunting seasons; the rut begins as early as the first week of September and runs approximately one month. Elk move between high-elevation timber bedding areas and lower private-land feeding areas as the season progresses. Black bears are present throughout, most active in mid-elevation berry and oakbrush zones from late summer through early winter. Mountain lions are resident, following deer and elk. Pronghorn occupy the lower sagebrush flats. Wild turkeys are present in riparian and lower-elevation timbered zones. The unit also supports sage grouse, golden eagles, and peregrine falcons in the Roan Plateau ACEC.
